Roof panel having solar cell

Abstract

A roof panel for a vehicle that has a solar cell is provided. Specifically, a solar cell panel that has a plurality of solar cell modules electrically connected is disposed on an inner surface of an upper surface of a vehicle body and a sticking member that protects the solar cell panel from an impact while having sticking characteristics is inserted and laminated between the inner surface of the upper surface of the vehicle body and the solar cell panel.

What is claimed is: 
     
         1 . A roof panel for a vehicle having a solar cell, comprising:
 a solar cell panel having a plurality of solar cell modules electrically connected is disposed on an inner surface of an upper surface of a vehicle body; and   a sticking member that protects the solar cell panel from an impact while having sticking characteristics is inserted and laminated between the inner surface of the upper surface of the vehicle body the solar cell panel.   
     
     
         2 . The roof panel of  claim 1 , wherein the solar cell panel further comprises:
 a substrate which is a flexible glass or plastic substrate having a thickness of about 0.01 mm to 1 mm and is deflectable based on a curved shape of the upper surface of the vehicle body.   
     
     
         3 . The roof panel of  claim 2 , wherein the plastic substrate may be a substrate manufactured using any one selected from a group consisting of: a polyethylene based polymer, a polypropylene based polymer, a polyester based polymer, a polyacryl based polymer, a polyimide based polymer, a polystyrene based polymer, a substrate made of a blend where polymer materials are mixed or a copolymer, and a substrate made by laminating polymer materials. 
     
     
         4 . The roof panel of  claim 2 , wherein the substrate has an ultraviolet ray transmission of 80% or greater. 
     
     
         5 . The roof panel of  claim 1 , further comprising:
 a finishing member attached to an inner surface of the solar cell panel; and   a separate sticking member that protects a solar cell panel from an external impact while maintaining sticking characteristics is laminated between tempered glass and a solar cell panel.   
     
     
         6 . The roof panel of  claim 5 , wherein the sticking member includes:
 PDMS (Polydimethylsiloxane), Polysilazane, PSSQ (polysilsesquioxane), a polysilicon based polymer, a polyurethane polymer, an epoxy based polymer, a synthetic resin, a natural rubber, a modified elastomer, a polyacryl based polymer such as PMMA (Polymethylmethacrylate), a styrene based copolymer;   a styrene based thermosetting copolymer such as P1 (Polystyrene), SBS (Styrene-Butadiene-Styrene Block Copolymer), SIS (Styrene-Isoprene-Styrene Triblock Copolymer), SEBS (Styrene-Etylene-Butylene-Styrene Block Copolymer), and ABS (Acrylonitrile-Butadiene-Styrene Copolymer);   a cellulose composite such as methylcellulose, ethylcellulose, and buthylcellulose, and PVB (Polyvinylbutyral), EVA (Ethylene Vinyl Acetate); and   a sticking member obtained by laminating members formed of the materials.   
     
     
         7 . The roof panel of  claim 5 , wherein a bonding layer is additionally laminated on one surface or opposite surfaces of the sticking member. 
     
     
         8 . The roof panel of  claim 1 , wherein a finishing member is attached to an inner surface of the solar cell panel, and a scattering layer is formed on one surface of the finishing member bonded to an inner surface of the solar cell module or the solar cell panel.
